my port motor has a slight bit of play at the shaft, when i flush my motors and engage the throttle i can hear a vibration. my starboard motor does not do this, any ideas on what to do. My throttle controls will not hold without me keeping pressure on them at all time. thanks

Don't quite understand what you are asking/saying, and there is a throttle friction setting on the control to prevent the handle just slipping back.
